Subfamily: Cuculliinae
Identification: Lines more strongly zigzagged than in D. dentilinea with black spot near tornus more conspicuous. In the latter, the am. and pm. lines usually do not touch and the black spot is often absent.
Wing Span: 3.0-3.4 cm
Life History: No specific information is known regarding larval foodplants of this species, but it probably feeds on herbaceous Asteraceae such as goldenrods (Solidago spp.) or gumweed (Grindelia spp.). The exotic tansy ragwort (Senecia jacobaeae) might be a foodplant in the Oregon Coast Range.
